What is the difference between conditional and unconditional probability?
Unconditional probability is the likelihood of an event happening regardless of any other factors. It is the probability of the event occurring when there are no conditions attached to it. Conditional probability, on the other hand, is the probability of an event happening given that another event has already occurred. It is the probability of the occurred. For example, the unconditional probability of rolling a six on a six-sided die is 1/6, or 16.67%. The conditional probability of rolling a six given that the first roll was a five is 1/6, or 16.
